It started as a folk song. I really liked the idea of acting on the spark you feel from a first encounter with somebody. They come and they go, and sometimes it's really inspiring. Even if you're the girl, you can ask for a number.

Have you ever had any "Call Me Maybe" experiences?

No, I haven't asked for a guy's number, but I've always wanted to. My tactic is to make eyes at someone.

How do you feel about it becoming a catchphrase?

That blows my mind! I had no idea it would turn into any of this. It's very exciting.
